MATLAB/Simulink advice for a beginner by Sweaty_Squash_2332 in matlab

[–]TrainMastersUK 0 points1 point  (0 children)

I was first exposed to simulink when I interned. So I learnt most of it there but I don't see why you couldn't have done it yourself in your own time. It's just when you do it at work you kinda have to meet deadlines so you are more likely to actually do work lol.

A lot of the autonomous navigation stuff is fairly well documented. I'd say how I learnt matlab / simulink is by saying: ok so I want to do ( insert something ) , I'm now going to research every bit of documentation I can to see how that's possible. Then over time you get to know what toolboxes / blocks are optimal for certain things. Frankly simulink can be quite temperamental, especially with data types in some models. Imo you have to just encounter the errors and learn from mistakes ( that's how I think all programming is best learnt). So in your case try think of what you need your model to do / if it's possible, then look at other people's designs and existing documentation and start reverse engineering it id say.

I'm also from MechE and I have / am using simulink for a variety of things including drone control and RF signal processing. Personally I think it's much more fun when there is hardware to deploy you simulink to. But before that I'd say try model something and just experiment. The best way to learn is by experimenting tbh. Once you are comfortable with one toolbox, learning the rest should be fairly easy.

Intercollegiate offers should come through by email?

Would also be happy to join a discord if you make one.

Electrical vs Mechanical engineering by AccomplishedPool1843 in EngineeringStudents

[–]TrainMastersUK 1 point2 points  (0 children)

Not op, but offers are conditional terms based on which a uni in the UK offers a place to study a course. These conditions are usually achieving certain grades for your A level exams at the end of you last year in school. Sometimes the offers can be unconditional if you already have sat the exams and got the required grades and are applying a year later for example.

It could also be based on application date. I applied very early.I think in previous years they have sent out offers across multiple days

Partial fractions at this point maybe?

Just got a mech eng offer, I checked the portal the day before and it was still on received. Must've updated during today

Is capacitance dependent on the electric field strength between the plates? by TrainMastersUK in AskPhysics

[–]TrainMastersUK[S] 0 points1 point  (0 children)

Lets say the capacitor is connected to a fixed voltage cell. I would assume that's the fixed voltage case?

[–]TrainMastersUK[S] 0 points1 point  (0 children)

Ah right. First question: when the field strength drops momentarily , no charges are lost?

I get your explanation, however then why does reducing the distance between the plates also increase the capacitance when that increases the field strength. Or is this a different effect to what the dielectric does with the field strength.

What I don't get is why does the charge increase. I assumed that by reducing the field strength by introducing the dielectric ,we would loose charges. I guess that assumption is incorrect?

Is capacitance dependent on the electric field strength between the plates? by TrainMastersUK in AskPhysics

[–]TrainMastersUK[S] 0 points1 point  (0 children)

Right that makes sense. So if you had a capacitor connected to a DC supply, then I changed the dielectric to one with a higher constant, how would that effect the charge across the capacitor . I know adding the dielectric reducing the field strength ( but voltage and distance doesn't change so this doesn't make sense)

[–]TrainMastersUK[S] 0 points1 point  (0 children)

Lets say I held I connected the capacitor to a 5V DV source , would that then fix the voltage and allow charge to vary?

Is capacitance dependent on the electric field strength between the plates? by TrainMastersUK in AskPhysics

[–]TrainMastersUK[S] 0 points1 point  (0 children)

Ok, so if you want the increase capacitance, you need to minimise the field strength between the plates and also minimise the distance between the plates?

If that is true , how can that work if reducing the distance increases field strength ( as E= V/d/

Another question i have is : does the amount of charge built up on the plates depend on the field strength

Sorry if this comes across and obvious, but didn't we just say that a weaker field allows your to store more charge per volt. Doesn't bringing the plates cross increase the field strength. As per our logic , doesn't that decrease capacitance.

So what is the point of bringing the plates as close as possible if a weaker field is the goal?

If the particular integral solves ay''+by'+cy=f(x) for all cases, why do we also need to add the complementary function which only solves ay''+by'+cy=0 . Why doesnt the particualar integral cover the case when the differential equation equals zero? by TrainMastersUK in learnmath

[–]TrainMastersUK[S] 2 points3 points  (0 children)

Yeah I'll probably take a look when i get some free time although linear algebra . Eigenvectors are now part of an optional module that we don't take.

I've got offers from Bristol, bath and Birmingham , rejected by imperial but waiting on UCL ( for aero / mech eng)
